ThisFinancial Analysis chapter focuses on the financial analysis of a virtual power plant project. The construction cycle, covering planning, development, construction, and operation stages. Major equipment and materials for data collection, networking, and system operation are detailed, along with software resources. The virtual power plant’s business model yields diverse benefits. Demand-side response offers subsidy income. The ancillary service market provides revenue from frequency modulation, voltage regulation, and standby services. Spot market trading brings gains from electricity sales and cost savings. Energy saving and emission reduction result in carbon trading and environmental subsidy revenues, while capacity compensation reduces expenditure and earns compensation. Overall, building a virtual power plant optimizes energy utilization, cuts electricity costs, stabilizes the grid, and promotes sustainable energy practices.
